Description

Control method of hot air blower for loosening and conditioning machine and electronic equipment

Technical Field

The application relates to the technical field of tobacco production, in particular to a control method of a hot air blower for a loosening and conditioning machine and electronic equipment.

Background

The outlet temperature of the loosening and conditioning process and the stability thereof have certain influence on the miscellaneous gas, the irritation and the like of cigarettes, and the CPK (Complex Process Capability index process capability index) of the batch outlet temperature of the loosening and conditioning process needs to meet the CPK more than or equal to 0.70 at present for stabilizing the quality of tobacco. The outlet temperature CPK is affected by the change of the temperature of the hot air of the loosening and conditioning machine.

The prior loosening and conditioning process enters a state of waiting for feeding after preheating. When the feeding is waited, the direct-blowing steam film valve is closed, so that the circulating hot air temperature gradually decreases, and as the waiting feeding time is longer, the circulating hot air temperature decreases more greatly, so that the circulating hot air temperature at the material head stage and the outlet temperature of the loosening and conditioning process slowly increase, and further, the standard reaching rate of the outlet temperature CPK is more than or equal to 0.70 is lower. And because tobacco production is influenced by a plurality of factors, the waiting feeding time of the loosening and conditioning process is not fixed, so that a feasible circulating hot air temperature control mode is needed to improve the standard reaching rate of the outlet temperature CPK more than or equal to 0.70 aiming at the waiting feeding stage of the loosening and conditioning process.

When the hot air temperature is in a temperature falling state, a measured value of the hot air temperature and a set value of the hot air temperature in the loosening and conditioning machine are obtained, a difference value between the set value of the hot air temperature and the measured value of the hot air temperature is determined, and if the difference value is larger than a preset threshold value, the target frequency of the hot air fan is set based on the current frequency of the hot air fan.

Specifically, the method judges whether the process is currently in a waiting feeding stage or not through the change state of the hot air temperature in the loosening and conditioning machine, and when the process is in the waiting feeding stage, the target frequency of the circulating hot air fan is reset based on the difference value between the set value of the hot air temperature and the measured value of the hot air temperature, so that the purpose of constant circulating hot air temperature is achieved through the change of the circulating hot air fan frequency, the circulating hot air temperature cannot be greatly reduced along with the extension of the waiting feeding time, and the standard reaching rate of the outlet temperature CPK is more than or equal to 0.70 is improved. And by adopting the control mode, the condensed water generation amount in the roller of the loosening and conditioning machine is small because the temperature fluctuation of the circulating hot air is small, so that the moisture of the tobacco flakes of the stub bar is prevented from being de-marked.

and obtaining a measured value of the hot air temperature every set time interval, and calculating a difference value between the set value of the hot air temperature and the obtained measured value of the hot air temperature.

That is, every set time interval, the difference between the set value of the air temperature and the obtained measured value of the hot air temperature is calculated, and if the difference is greater than a preset threshold value, the target frequency of the hot air fan is set based on the current frequency of the hot air fan. Namely, the frequency of the lower hot air fan is timely adjusted every a period of time, so that the temperature of hot air can be more quickly increased to a required temperature set value, and the CPK of the outlet temperature is improved.

Specifically, the applicant researches that the shortest time for spreading the materials before loosening and conditioning is about 8 minutes, so that the temperature of circulating hot air needs to reach a set value within 8 minutes before the materials are put on a scale. The interval time may be generally set to 0.5 to 3 minutes, and preferably, the set time may be set to 1 minute to ensure that the best effect is achieved.

The frequency of the circulating hot air fan is increased stepwise, namely, the frequency of the hot air fan is increased by a preset increasing frequency value every time, so that the stable and rapid hot air temperature reaching of a set value of the hot air temperature can be ensured, and the adverse effect on the moisture content of the stub bar material caused by larger fluctuation of the hot air temperature in the heating process is avoided. And the maximum frequency of the hot air blower is limited to be set as the upper limit value of the set frequency, so that the supply capacity of the process and the equipment can be considered, and the efficiency of the process can be improved.

The method for increasing the frequency of the circulating hot air fan in a stepped mode can ensure that the hot air temperature stably and rapidly reaches the set value of the hot air temperature, and avoids the adverse effect on the moisture content of the stub bar materials caused by larger fluctuation of the hot air temperature in the heating process. And the maximum frequency of the hot air blower is limited to be set as the upper limit value of the set frequency, so that the supply capacity of the process and the equipment can be considered, and the efficiency of the process can be improved.

Specifically, the method adopts the step-type reduction of the frequency of the circulating hot air fan, namely, the frequency of the hot air fan is reduced by a preset reduction frequency value each time, so that the hot air temperature can be ensured to be stably maintained at the set value of the hot air temperature, and adverse effects on the hot air temperature caused by frequency fluctuation are avoided. And the minimum frequency of the hot air blower is limited to be set as the lower limit value of the set frequency, so that the hot air temperature can be ensured to meet the process requirement.

Detailed Description

The application will be further described with reference to specific examples and figures. It should be understood that the illustrative embodiments of the present disclosure, including but not limited to, control methods, electronic devices, media and program products for a hot air blower of a loose conditioning machine, are described herein in terms of specific embodiments only and are not limiting of the application. Furthermore, for convenience of description, only some, but not all, structures or processes related to the present application are shown in the drawings.

Further advantages and effects of the present application will become apparent to those skilled in the art from the disclosure of the present specification, by describing the embodiments of the present application with specific examples. While the description of the application will be presented in connection with a preferred embodiment, it is not intended that the application be limited to this embodiment. Rather, the purpose of the application described in connection with the embodiments is to cover other alternatives or modifications, which may be extended by the claims based on the application. The following description contains many specific details for the purpose of providing a thorough understanding of the present application. The application may be practiced without these specific details. Furthermore, some specific details are omitted from the description in order to avoid obscuring the application. It should be noted that, without conflict, the embodiments of the present application and features of the embodiments may be combined with each other.

In order to solve the problems that the outlet temperature of the loosening and conditioning process in the prior art rises slowly, and the standard reaching rate of the outlet temperature CPK is more than or equal to 0.70 is lower, the circulating hot air temperature of the loosening and conditioning machine can be controlled in the following two ways.

Mode one: when the circulating hot air temperature is reduced in the waiting feeding stage, the direct-blowing steam film valve is manually opened, and the circulating hot air temperature is constant by utilizing the direct-blowing steam. Fig. 1 is a graph showing the comparison of the effects of the circulating hot air temperature change trend, the outlet temperature change trend and the outlet moisture change trend in the loosening and conditioning machine in the control mode, wherein in fig. 1, there are two areas, namely a light gray area and a dark gray area, the upper boundary line and the lower boundary line of the dark gray area are respectively an upper tolerance limit value and a lower tolerance limit value, the upper boundary line and the lower boundary line of the light gray area are respectively an upper standard limit value and a lower standard limit value, as shown in fig. 1, the outlet temperature in the control mode rises faster, and the outlet temperature of the material head can reach a normal level after 40S, however, the mode has the condition that the material head stage of the circulating hot air temperature exceeds the upper tolerance limit value and the outlet moisture of the material head exceeds the upper tolerance limit value (as marked by a dotted line box in fig. 1), and the quality of tobacco produced is affected.

Mode two: and in the feeding waiting stage, when the temperature of the circulating hot air is reduced, switching the feeding waiting state into a preheating state, and carrying out preheating again. Fig. 2 is a graph showing the comparison of the effects of the trend of the temperature of the circulating hot air, the trend of the temperature of the outlet and the trend of the moisture of the outlet in the loosening and conditioning machine in the control mode of mode two, wherein in fig. 2, there are two areas, namely a light gray area and a dark gray area, the upper and lower boundary lines of the dark gray area are the upper limit value and the lower limit value of tolerance, respectively, and the upper and lower boundary lines of the light gray area are the upper limit and the lower limit value of standard. As shown in fig. 2, the outlet temperature in this control mode rises faster, and the outlet temperature of the stub bar reaches a normal level after 50S, but this mode also has a case where the circulation hot air temperature stub bar exceeds the tolerance upper limit value and the moisture of the stub bar outlet exceeds the tolerance upper limit value (as indicated by the dotted line box in fig. 2). When the batch stub bar tobacco blocks are just weighed, the state of waiting for feeding is switched to the preheating state, and the situation can cause batch stub bar breakage, which is disadvantageous in tobacco production.

Based on the above, the application provides a control method of a hot air blower for a loosening and conditioning machine and electronic equipment, so as to solve the technical problems found in the research process.

The control method for the hot air blower of the loosening and conditioning machine comprises the steps of judging the change state of the hot air temperature in the loosening and conditioning machine, obtaining a measured value of the hot air temperature and a set value of the hot air temperature in the loosening and conditioning machine when the hot air temperature is in a temperature falling state, determining the difference value between the set value of the hot air temperature and the measured value of the hot air temperature, and setting the target frequency of the hot air blower based on the current frequency of the hot air blower if the difference value is larger than a preset threshold value.

In some embodiments of the present application, obtaining a measured value of a hot air temperature and a set value of the hot air temperature in the loosening and conditioning machine, and determining a difference between the set value of the hot air temperature and the measured value of the hot air temperature, and if the difference is greater than a preset threshold, setting a target frequency of the hot air fan based on a current frequency of the hot air fan, including: acquiring a set value of the hot air temperature, acquiring a measured value of the hot air temperature every set time, calculating a difference value between the set value of the hot air temperature and the acquired measured value of the hot air temperature, and if the difference value is larger than a preset threshold value, increasing the current frequency of the hot air fan to serve as a target frequency of the hot air fan.

The control method of the hot air blower for the loosening and conditioning machine can be applied to the tobacco loosening and conditioning process. The application adopts the stepped increase of the frequency of the circulating hot air fan, can ensure that the hot air temperature stably and rapidly reaches the set value of the hot air temperature, and avoids the adverse effect on the moisture content of the stub bar material caused by larger fluctuation of the hot air temperature in the heating process. According to the scheme, the frequency of the circulating hot air fan is timely adjusted, the purpose of constant circulating hot air temperature is achieved through the change of the frequency of the circulating hot air fan, the circulating hot air temperature cannot be greatly reduced along with the extension of waiting feeding time, and the standard reaching rate of the outlet temperature CPK is more than or equal to 0.70 is improved. And by adopting the control mode, the condensed water generation amount in the roller of the loosening and conditioning machine is small because the temperature fluctuation of the circulating hot air is small, so that the moisture of the tobacco flakes of the stub bar is prevented from being de-marked.

Embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

Referring to fig. 3, in one embodiment of the present application, a control method of a hot air blower for a loose conditioning machine includes:

s101: and judging the change state of the temperature of hot air in the loosening and conditioning machine.

Specifically, the state of change of the hot air temperature can be judged by collecting the hot air temperature measurement value Tc. For example, a measured value Tc of the hot air temperature in the loosening and conditioning machine is obtained in real time, the change state of the hot air temperature is judged based on the measured value Tc of the hot air temperature obtained in real time, and if the measured value Tc_new of the hot air temperature at the current moment is smaller than the measured value Tc_last of the hot air temperature at the last moment, the hot air temperature is judged to be in a temperature falling state.

S102: when the hot air temperature is in a temperature falling state, a measured value Tc of the hot air temperature and a set value Ts of the hot air temperature in the loosening and conditioning machine are obtained, a difference value DeltaT between the set value Ts of the hot air temperature and the measured value Tc of the hot air temperature is determined, specifically DeltaT=Tc-Ts, and if the difference value DeltaT is larger than a preset threshold Deltato, the target frequency of the hot air fan is set based on the current frequency Fc of the hot air fan.

Specifically, the preset threshold Δto may be 0 To 5 ℃, the measured value Tc of the hot air temperature may be obtained every time interval, and the difference Δt=tc-Ts between the set value Ts of the hot air temperature and the obtained measured value Tc of the hot air temperature is calculated.

When the difference value delta T is smaller than a preset threshold value delta To, acquiring the current frequency Fc, a preset increasing frequency value Fp and a set frequency upper limit value Ft of the hot air blower, further calculating the sum F=Fc+fp of the current frequency Fc and the preset increasing frequency value Fp of the hot air blower, and judging the magnitude relation between the sum F and the set frequency upper limit value Ft, wherein when the sum F is smaller than the set frequency upper limit value Ft, the sum F is taken as the target frequency of the hot air blower, namely the frequency of the hot air blower is updated To F; when the sum F is greater than or equal to the set frequency upper limit value Ft, the set frequency upper limit value Ft is taken as the target frequency of the hot air fan, so that the frequency of the hot air fan is updated to Ft.

Further, when the difference Δt is equal to or smaller than 0 (i.e., the measured value of the hot air temperature reaches the set value of the hot air temperature), the current frequency Fc, the preset reduced frequency value Fm, and the set frequency lower limit value Fl of the hot air blower are obtained, the difference F2 between the current frequency Fc and the preset reduced frequency value Fm of the hot air blower, specifically f2=fc-Fm, is calculated, and the magnitude relation between the difference F2 and the set frequency lower limit value Fl is determined. Wherein,

When the difference F2 is larger than the set frequency lower limit value Fl, taking the difference F2 as the target frequency of the hot air fan, namely setting the frequency of the hot air fan as F2; when the difference F2 is less than or equal to the set frequency lower limit value Fm, the set frequency lower limit value Fm is set as the target frequency of the hot air fan, i.e., the frequency of the hot air fan is set as Fm.

Specifically, as shown in table 1, when the set time is set to 1min and the preset increase frequency value is set to 5Hz, a more excellent effect can be achieved.

Table 1 effect comparison table of different preset increasing frequency values and setting time

The application adopts the step-type gradual increase of the frequency of the circulating hot air fan to the upper limit value of the set frequency, can ensure that the hot air temperature stably and rapidly reaches the set value of the hot air temperature, so that the circulating hot air temperature can not be greatly reduced along with the extension of waiting feeding time, the standard reaching rate of the outlet temperature CPK is more than or equal to 0.70 is further improved, and the adverse effect on the moisture content of the stub bar material caused by larger fluctuation of the hot air temperature in the heating process can be avoided. Because the temperature fluctuation of the circulating hot air is small, the condensate water production amount in the roller of the loosening and conditioning machine is small, and further, the moisture removal of the tobacco flakes of the stub bar is avoided. In addition, after the measured value of the hot air temperature reaches the set temperature value, the frequency of the hot air fan is further reduced in a stepwise reduction mode, so that the hot air temperature is ensured to be stably maintained at the set value of the hot air temperature, and adverse effects on the hot air temperature caused by frequency fluctuation are avoided.

Referring to fig. 4, a specific flow chart of a control method of a hot air blower for a loosening and conditioning machine according to an embodiment of the present application is shown.

In this embodiment, the PLC firstly executes step S201 to collect the measured value of the circulating hot air temperature every interval of the set time, then the PLC executes step S202 to compare the collected measured value of the circulating hot air temperature with the set value of the circulating hot air temperature, and determine whether the measured value of the circulating hot air temperature reaches the set value, if the measured value of the circulating hot air temperature does not reach the set value, step S203 is executed to stepwise adjust the frequency of the hot air fan (for example, increase the frequency of the hot air fan by 5 Hz), and it should be noted that the upper limit value of the frequency of the hot air fan is 50Hz, that is, once the frequency of the hot air fan reaches 50Hz, even if the measured value of the circulating hot air temperature does not reach the set value yet, the frequency of the hot air fan is not increased any more. When the measured value of the circulating hot air temperature reaches the set value, step S204 is executed to gradually decrease the frequency of the circulating hot air blower until the frequency is decreased to the set frequency lower limit value.

Fig. 5 is a schematic diagram of a circulation hot air temperature change trend, an outlet temperature change trend and an outlet moisture change trend in the loosening and conditioning machine after the hot air blower of the loosening and conditioning machine is controlled based on the control method provided by the application, wherein in fig. 5, two areas are a light gray area and a dark gray area, the upper boundary and the lower boundary of the dark gray area are respectively an upper tolerance limit value and a lower tolerance limit value, the upper boundary and the lower boundary of the light gray area are respectively a standard upper limit and a standard lower limit value, and in the control mode provided by the application, the outlet temperature rises faster, and the outlet temperature of a 60S material head can reach a normal level, so that the standard reaching rate of the outlet temperature CPK is ensured. In addition, the water content of the circulating hot air temperature stub bar stage and the stub bar outlet in the control mode of the application are within the tolerance range, and the quality stability of stub bar tobacco is improved.
